Application filed December 28, 1918. Serial No. 268,594,

Ward the left-hand end of the platen frame;

To all whom it may concern;

Be t known that 1,..Cotn1us VAN Econ, a citizen of the United States, residing in Knoxville, in the county of Knox and Stateof an improvement upon the device dis closed in Patent No. 915,875, to McCor mack, dated March 23, 1909.

In said patent, a label-holding device is placed at one end of the platen, and comprises a feed plate or apron which pr%ses against the platen below the printing line, in addition to rolls which run upon the platen just above the printing line, and which are releasable to permit the withdrawal of the labels. These rolls are carried upon a short arbor or stud, which at one end is mounted or anchor upon an end portion of the platen frame. Since it is important. that these parts should be of little weight, they are usi'ially made thin and weak; and, in said patent, a brace is extended forwardly from a platen-frame rod to support said arbor at a point between said rolls. I

It is found in practice that not only is it necemary to release the rolls in order" to withdraw the typed label, but it may also occasionally happen that a long label will foul said. brace arm. it has also been found that if the inachine is, used for ordinary letter-writing, employing large work-sheets, the width of the sheet is limited by the necessity of aroiding the fouling of said brace arm.

The principal object of my invention is to improve the lv'lcCormaok machine, so as to make possible the automatic of the labels from the machine, and also to render the machine capable of Writing upon wider large worksheets than heretofore, or of writing longer lines upon said Work sheet-s.

in order to attain these ends, in place of the cross-brace or b-mcin a .1 353 seen in said patent, I extend a cross *rom the same point of engagement wn ar bor (between the feed rolls thereon} itwardly past the left-hand feed roll am; to-

and then I bend it back and carry it to a rod-aforesaid. By the substitution of the new cross-brace arm which extends along the inner roll before reaching back tojthe rod, it is found that labels can= 'be' fed through the machine and emerge therefrom without the necessity of releasing the labeL' feeding rolls, and also that-the entire print point of engagement with the pl'aten'irame ing field of the platen can be used for the v large work-sheets, whereas heretofore a substantial portion of the printing field at. the left-hand end of the platen could not be used, on account of the bar which said arm constituted against the egress of the sheets from the machine.

In the accompanying drawings,

Fig. 2 is-aplan of the platen and appurtenances, inc uding my improved cr stbrace.

Fig. 8 is a sectional side elevation bffthe mechanism. v 1

Fig. 4 is a perspective top View showing the improved method of bracing the arbor which carries the roll brackets.

As set forth in said patent, a cylindrical platen 1 is journaled in ends 2 and 3- of a" platen frame 4. The platen frame comprises a rod 5 rigidly connecting the ends 2, 3 said rod arranged at the rear of the platen 1 and at the upperportion of the platen frame.

The labels may be introduced at the rear of the platen and fed forwardly by the usual bottom rolls 6, 7, and guided up to the printing point by a plate 8; and they may be en' gaged above the printing point by rolls 9, 10, which hold the label or card firmly against the platen, being for this urpose mounted upon inner andv outer pm ets 11, 12, as set forth in said patent. These brackets are journaled upon a projecting arbor 13, said arbor being anchored only to the left-hand platen frame end 2, this being done by meansof abracket 14 in which the arbor is fixed; said bracket being secured to the plat-en frame end by a screw 15.

In""oi'der to support the right-hand end portion of the arbor in such a manner thatthe pressure of the rolls 9, 10, upon the sheet or platen shall be about equal, so as to insure even feed 0 the label or Workpiece, I attach to the arbo 13 a supporting boss 16 between the brackets 11, 12, so that the arbor may be supported With sufficient firmness for the purpose. This boss is formed upon a crossemerge free from the machine regardless of the cross-brace 17, so that it is no longer necessary to release the rolls 9, 10, (dotted line position at Fig. 3) in order to Withdraw the labels. Moreover, the entire printing field of the platen may be employed for wide sheets, since they no longer foul the crossbrace. Variations may be resorted to Within the scope of the invention, and portions of the improvements may be used Without others. Having thus described my invention, I claim: I

' 1. The combination Witha revoluble platen and a platen frame, of an arbor fixed at one end upon the end of the platen frame and projecting along the platen, inner and outer brackets journaled upon the proj ecting portioiri of arbor and carrying feed rolls to run upon the front of the platen, the

brackets being rotatable about said arbor to release the rolls from the platen, a fixed rod extending from the end of the platen frame along the platen at the rear thereof, and a cross-brace connecting said arbor to said rod, said cross brace engaging said arbor at a point between said roll brackets, and extending along the arbor clear of the inner bracket and past the inner roll, and 'bent to extend back to a point of enga: :ment with said rod.

The combination with a revoluble platen and a platen frame, of an arbor fixed at one end upon an end of the platen frame and projecting along the platen, a bracket.

journaled upon' the projecting portion of said arbor and carrying a feed roll to press the Work against the platen, the bracket being rotatable about said arbor to release the roll from the platen, a rod fixed to said end of the platen frame and extending along the platen at the rear upper portion thereof, and a cross-brace connecting the projecting portion of said arbor to said fixed rod, said cross brace attached to the arbor at a point beyond said roll bracket, and extending thence along said bracket and past said roll toward the end of the platen frame upon which said arbor is mounted, and there bent to extend rearwardly to a point of attachment to said a rod.
